Effects of density stress and soil productivity on size, mortality and nitrogen fixation in artificial populations of seedling red alder (Alnus rubra Bong.)

Creator:: Smith, Nicholas J.
Abstract:: Red alder (Alnus rubra Bong.) seedlings were grown at three initial spacings (8 x 8 cm, 4 x 4 cm, and 2 x 2 cm) and on two soil types (forest soil and river loam) under greenhouse and lath house conditions for 525 growing days. There were seven harvest dates,...

Water stress, fertilization and light effects on the growth of nodulated, mycorrhizal red alder seedlings

Creator:: Koo, Chang Duck
Abstract:: Red alder (Alnus rubra Bong.) seedlings fertilized with NH4NO3 or inoculated with a pure culture Fran/cia and inoculated with live or dead spores of the mycoirhizal fungus Alpova diplophloeus (Zeller & Dodge) Trappe & Smith were grown in a growth chamber or in a greenhouse for six months Frankia inoculation...

Genetic differences in red alder populations along an elevational transect

Creator:: Campbell, Allan, 1936-, Ching, Kim K., and Oregon State University. Forest Research Laboratory
Abstract:: "Because forest managers and geneticists need basic information about natural variations in populations of red alder, we studied conelet and seed characteristics, as well as early growth, of this species along an elevational transect in the Coast Range of Oregon."--P. [1].

Influence of soil and rhizosphere actinomycetes on Frankia infection and nitrogenase activity in Alnus rubra Bong

Creator:: Rojas-Melo, Nestor S.
Abstract:: Nodulated roots of young red alder trees and soil samples were collected from a 5 year old clearcut on Mary's Peak, Oregon. Frankia was isolated from root nodules, andactinomycetes from nodules, roots, and soil. A total of 229 pure culture actinomycete isolates were recovered: 131 colonies from root surfaces, 52...

Seasonal and diurnal trends of leaf water potential and stomatal conductance of red alder (Alnus rubra Bong) growing along a density gradient in western Oregon

Creator:: Lu, Shengjun
Abstract:: Three Nelder plots of 3-year-old red alder (Alnus rubra Bong) were used for this study at the Cascade Head Experimental Forest, Oregon in the growing season of 1988 at an elevation of 330 meters. Each Nelder plot represented a range of densities from 238 to 101,219 trees per hectare. The...

Seasonal estimates of nitrogen fixation by Alnus rubra and Ceanothus species in western Oregon forest ecosystems

Creator:: Kim, Dong Yeob
Abstract:: Two case studies of 5 ecosystems were used to examine the nitrogen fixation rate of red alder (Alnus rubra Bong.), varnishleaf (Ceanothus velutinus var. laevigatus (Hook.) T. & G.), deerbrush (C. i ntegerrimus H. & A.), and snowbrush (C. velutinus var. velutinus Dougl. Ex Hook). The first case study assayed...

The role of density and proportion in allometric equations of Douglas-fir and red alder seedlings

Creator:: Cooke, Pamela T.
Abstract:: Allometric equations are useful tools for predicting tree biomass when direct measurements are impractical. Any factor affecting plant growth can be a significant variable in allometric equations. Density and species proportion are spatial variables that influence tree growth and should be considered when developing allometric equations. This consideration is especially...

The structure and dynamics of red alder communities in the central coast range of western Oregon

Creator:: Carlton, Gary C.
Abstract:: Red alder (Alnus rubra Bong.) is a fast-growing pioneer species that colonizes disturbed forest sites west of the Cascade Mountains in the Pacific Northwest. Streambottoms, toe slopes, and mass movement of surface soils have historically provided the scarification and soil moisture necessary for successful regeneration of red alder. During the...
